A refracting func_brush.

The Refract shaders distorts objects behind it. It is similar to Water, but does not reflect and so is not restricted to flat surfaces. Can be used to create distorting glass windows etc.

Note.pngNote:Will not work when applied to world brushes (including func_detail).

Syntax

Refract
{
	$normalmap ...
	$dudvmap ...
	$refracttint "[1 1 1]"
